Patented May 30, 1933 [UNITED STATES PATENT JAMES O. FINK, OF PETROIT, MICHIGAN, ASSIGNOR 'IO CONTINENTAL MOTORS OORIOBA- TION, OF DETROIT, liIICHIGAN, A CORPORATION OF VIRGINIA I ENGINE Application filed May 28,

' A still further feature of my invention resides, in the provision of a cover which protects the parts of the engine otherwise exposed from moisture, dirt and the like, reference being made particularly to the spark plugs and terminal wiring as well as the connections and joints associated with the cylinder block and the assembly structure seated thereon.- j

Additional objects and advantages of my invention will be apparent as this specification progresses, reference being made for illustration to the accompanying drawlng forming a part hereof and in which the singlefigure is illustrative of one preferred embodiment of my invention. V

The single figure illustrated represents a sectional elevation view through one of the cylinders of the engine, the section belng taken transversely thereto.

Reference character A represents the cylinder block having the usual cylinders 10 spaced along the block and in the engine illustrated one or more sleeve valves 11 are adapted to operate between cylinder 10 and the customary piston 12 whereby the sleeve intake and exhaust ports 13 and 14 perform the usual valving functions in cooperation with the cylinder intake and exhaust ports 15 arid 16 respectively. The engine illus trated is of the single sleeve type known as the Burt-McCollum engine wherein the sleeve is given a combined reciprocating and oscillating movement to accomplish the porting in a customary well known manner.

Seated on the upper face of the cylinder block A through the intermediary of a gas- 1931. Serial No. 540,556.

ket 17 is a structure B providing av jacketed cylinder head assembly for the engine. This structure B consists in the present embodiment of a cylinder head structureor member 18 adapted to extend within the upper portion of the sleeve 11 andcylinder 10, the cylinder head having a flange 19 secured by fastening members20 to thecylinder block structure A. The cylinder head is also formed with a portion 21 which is generally cup-shaped and open at its upper end 22 for receiving andhousing a spark plug 23 the terminals .24 of which are open to the combustion chamber 25.

A Water jacket member or structure 26 ture assembly B, the cover 26 having a flange 27 seated on the upper face of the cylinder block A and this flange is extended outwardly at opposite sides of the engine whereby a portion 28 thereof slightly overhangs the side face 29 of the cylinder block A. The cover 26 is preferably secured to the cylinder head 18 by any suitable means such as the nut 30 threadedly engaging the portion 21 of the cylinder head. I

An important feature ofmy invention resides in the provision ofa cover 31 which comprises a furtherv element of the strucis in the general form of a hood extending A longitudinally of the engine and adapted to bridge the engine transversely. thereof, whereby the spark plugs 23 together-with their terminal wires 32 and the other parts of the engine which would be otherwise ,exposed, are efl'ectively and conveniently protected from moisture, dirt, etc.

The cover 31 is preferably a sheet metal stampingin order to provide a low cost structure and to also facilitate the assembly and disassembly of the cover from the engine structure. Thus by reason of such construction the cover 31 is formed with the downwardly extending side portions or legs 33 which are adapted to yieldingly or springingly engage a convenient portion of the engine such as the outwardly extending overhanding portions 28 of the cover 26. For cooperation with these overhanging portions I have formed the sides 33 with a recess 34 terminating downwardly in a longitudinal edge 35 preferably rolled in general circular form as illustrated in the drawing whereby the lower ends of the cover will be readily guided into firm position when the cover is moved downwardly for engagement as illustrated.

In placing the cover in position, it is pressed downwardly whereby the edges 35 will engage the upper curved surfaces of the flange 27, the edges 35 being guided outwardly around the overhanging portions 28, the sides or legs 35 yielding to permit this movement. After the edges 35 are passed below the overhanging portions 28 theedges 35 will then spring inwardly against the side faces of the cylinder block and the recesses 34 in the side walls of the cover will receive the overhanging portions 28 whereby the cover will be securely but removably held in position. In removing the cover it is only necessary to lift the cover from the engine, the side walls 34 springing outwardly to permit such removal.

Preferably the ends of the cover 31 longitudinally of the engine are open, permitting the terminal wires 32 from the spark plugs to be conveniently passed through one or both of the open ends.

By reason of my invention it is possible to very quickly obtain access to the spark plugs and other parts of the engine by simply lifting the cover from its position where it is yieldingly held in place. This is accomplished without the necessity-0f the customary nuts and bolts generally used in cover constructions and which require con siderable time and bother incident to their assembly or removal.

In many instances I provide a single cover which extends the full length of the engine, but if desired the cover structure may be constructed of two or more sections. One use of a sectional cover is contemplated, in which a heater tube (not shown) extends across the top of the motor midway of its length, and in this case the cover may be split transversely substantially at the middle and the sections may be interlocked together if so desired.

It will be apparent that various changes and modifications may be made as a result of my said invention and within the spirit and scope thereof, and it is not my intention to limit my inventionto the specific construction and arrangement of parts illustrated, except as may be specifically recited in the appended claims.

What I claim as my invention is:

1. In an engine having a cylinder structure, a cylinder head and a water jacket structure for the cylinder head; a cover for the water jacket structure having a securing portion adapted to spring over a portion of said water jacket cover.

2. In an engine having a cylinder structure, a cylinder head and a water jacket structure for the cylinder head; a cover for the water jacket structure having a securing portion adapted to spring over a port-ion of said water jacket cover, said water jacket cover portion projecting laterally from the cylinder structure.

3. In an engine having a cylinder block structure and a structure secured to said block providing a jacketed head for the cylinder of said block; a cover bridging the block transversely and including means yieldingly engaging one of said structures forsecuring the cover in position.

4, In an engine having a cylinder block structure and a structure secured to said black providing a jacketed head for the cylinder of said block; a cover for said jacketed head structure provided with depending legs springingly engaging one of said structures.

5. In an engine having a cylinder block structure and a structure secured to said block providing a jacketed head for the cylinder of said block; one of said'structures having a portion overhanging the other, and a cover for said jacketed headstructure springingly engaging saidoverhanging por-' tion.

6. In an engine having a cylinder block structure and a structure secured to said block providing a jacketed head for the cylinder of said block; and a sheet metalcover for said jacketed head structure adapted to yieldingly engage one of said structures. 7. In an engine having a cylinder block structure and a structure secured to said block providing a jacketed head for the cylinder of saidv block; one of said structures having a portion overhanging the other, and a sheet metal cover for the engine adapted to springingly engage said overhanging portion.
